Blood is water

Inquisitive sisters Klára and Gábina have everything under control in the village of Vlčice. Gábina's fiancé, Jaroslav, is planning their wedding, but Gábina keeps finding excuses to postpone it. Klára is dating Miloš, but she can't help but notice that private eye David still has his eye on her, even after all these years and despite her and her sister constantly thwarting his investigations. To top it all off, their stepsister Kamila is causing them trouble, visiting Vlčice more often than is good for anyone.
